Text (english):
"Yes, it took a long time, and improvements were also constantly being made to the adapters, which then proved their worth in the long-term test. One must not forget that the topic with the rather hot 12VHPWR connections is richly complex and therefore quick fixes of any kind are completely forbidden. Of course, you could have just soldered a few components onto a board and hoped nothing would go wrong. The only thing is that this is neither sustainable nor fair to the buyers. And you can ruin your reputation to boot."

"In general, today’s review does affect all graphics cards that use external power connections, but the rather small 12VHPWR adapter and the ability to blow through a whopping 600 watts (and more) on some GeForce RTX 4090s obviously tightens things up a bit. Today, I’ll show how using just two pads can lower the connector temperatures in the 12VHPWR by up to 15 (!) Kelvin and also explain where the high temperatures primarily originate and why both the Founders Edition air cooler and all GPU waterblocks tested so far have some sort of design flaw. But you have to come up with it first…"
